More about this archive record

Can I still buy BTTAY shares?

No. BTTAY stopped trading on public markets, so the shares are not available through a broker. Anything you see quoted for BTTAY elsewhere is historical data, not a live market.

Are the figures on this page current?

No. Every number here is the last value recorded before BTTAY stopped trading. Nothing on this page updates, and none of it is a current quote.

Why does this page still exist?

Because people still search for what happened to Biotest AG. An archived profile that states the delisting plainly is more useful than a dead link — provided it is labelled as history, which is what this page does.
